 *  ValueMap is used in conjunction with Scouter and MLSender to carry the information declared by IMonitorSvc's declareInfo. 
 *  It converts the variable to a void* pointer and stores its type information in an enum. This way, the variable can be converted
 *  to its original form when being written or published.
